UNITED STATES EVELYN C. Sl/VEETSER, OF'BROOKLYN, NEW YORK.

OPEN-AIR CRIB.

Application filed October 8, 1924. Serial No. 742,287.

To all whom it may concern Be it known that I, EVELYN C. SwEE'rsER, acitizen of the United States, residing in the borough of Brooklyn,county of Kings, city and State of New York, have invented new anduseful Improvements in an Open-Air Urib, of which the following is aspecification.

My invention relates to open air cribs or beds constructed so that theymay be attached to a window frame or similar structure whereby a childcan in perfect safety be placed in the open air for unlimited periods oftime, thereby leaving the mother or nurse free to engage in household orother duties but with full opportunity to watch over and attend to anywants or needs of the child.

My invention will have special advantages in cities, where it hasheretofore been only possible to give a child thenecessary benefits offresh air, by the use of a baby carriage or perambulator which involvesconsiderable inconvenience and the enforced absence of the mother ornurse from the home during the airing period of time.

It will be seen from the drawings and description herewith that thedevice combines all the required elements of strength, safety, adatability for use in any and all kinds of win ows, with protectionagainst drafts, sun glare, or inclement weather of any kind, and alsothat my structure can be made economically, and put together or takenapart, and secured in position on the window frame with a minimum oftime and effort.

Other advantages and benefits are set forth in the following detaileddescription and in the drawings in which Fig. 1 is a front elevation ofthe device positioned in a window.

Fig. 2 is a side view of same with the window frame in section.

Fig. 3 is an enlarged fragmentary detail view of the supporting rod andbrace and the means for locking the upright members of the structure tothe bottom member.

Fig. 4 is a detail view of the clamp 18.

The preferred form of my invention shown herewith comprises a rigidmetal base frame 10, one member 11 of which may be secured to the sill12 of the window frame. To make the device portable and easy to assembleand take apart when desired, the bottom member 13 of the crib is securedto the frame 10, and the three side members 14, 15 and 16 are madeseparately and locked to the base frame 10 by the rotatable hooks 17which are threaded at one end and inserted in openings tapped in theside members of the said base frame.

To secure the front edges of the-members 14, 15 and 16 together, Iemploy clamps 1818 which consist of an arched member 19 in the concavedside of which the upright frame members 20-20 are gripped, the clampsbeing locked and held in position by the screws 2121 which pass throughthe arched member 19 and have upon their threaded ends the washers 2222and the knurled nuts 2323. The said clamps and the hooks 17 serve toprovide a strong, secure receptacle in which a child may be left inperfect safety.

As an additional support the braces 24-24 are secured at their upperends 2525 to the upright sides of the window frame and at their lowerends openings are provided through which the threaded ends of the rod 26pass, nuts 27 and 28 serving to lock the side members of the base frame10 against any lateral movement.

A rear wall member 15 may be used when desired to prevent the child fromeither falling or climbing out of the crib into the room, outside ofwhich the structure is located.

To prevent any vertical movement of the assembled structure the U-shapedlocking devices 2929 are hooked over the said side members of the baseframe the lower outside ends having openings 30 30 through which theends of the rod 26' pass.

It will be seen from the foregoing that this device while easy to takeapart. assemble or .place in position in a window, is very rigid,

strong and safe. As shown herewith a good weight of metal mesh isemployed for the bottom and sides of the structure but any othersuitable material could be utilized, and if desired a top or cover ofthe same material could be employed although in many cases fabricawnings and side pieces would be advantageous to shield the child fromsun glare or currents of air.

If desirable for any reason this device could also be positioned insidethe room by attaching the member 11 to the inner window sill anddropping the braces 2424 to form legs reaching to and supported by thefloor of the room.

I claim In an open air crib the combination of the following elements; abase frame member adapted to be secured to a Window frame; sectionalfront and side members adapted to be locked in position on the said baseframe member; means for locking the said front and side members on thesaid base frame member and comprising rotatable hooks mounted in theframe of the said base frame member and adapted to engage by theirhooked ends with the frames of the said front and side members; meansfor locking together the said front and side members and comprisingarched clamps adapted for engagement on their concave sides With theupright frame members of the said front and side members, and means forlocking the said arched clamps in engagement with the said upright framemembers; and means for holding the assembled structure against lateralor Vertical movement comprising and hooks adapted to lock together theside members of the base frame and the ends of the said rod.
